When the engine starts it is cold, as it warms up it builds heat which causes condensation to form. Since heat rises so does the condensation as it tries to excape through the PVC in the valve cover. As the engine cools it has the same effect, the valve covers are thin metal or aluminum they cool quickly but the oil in the pan is hot which causes the condensation to form on the valve covers.
Check the oil dipstick. if it is milky white that is evidence of water or moisture. also remove the oil fill cap from the valve cover and look for moisture
Please restate the question. What are you talking about? Valve cover gaskets, valve cover, what? need a valve cover
There are valve cover bolts around the perimeter of the valve cover. You want these tight but not as tight as you can get them.
# The PCV valve is located in the valve cover # Detach the hose from the valve then unscrew the valve from the valve cover
it is on the valve cover, usually in the driver side valve cover. If you have a 2.2 L engine, it doesn't have a serviceable PCV valve, it is built into the valve cover.
As with all valve gaskets it is located between the valve cover and the head. To get to it you undo all bolts holding the valve cover on and then pull valve cover off. you will find it on the valve cover/ head contact point.
Remove the valve cover.....scrape off old gasket.....clean gasket surface on valve cover....apply gasket sealent to valve cover gasket surface.....set gasket in sealent.....reinstall valve cover.
Assuming you mean "valve cover gasket", the gasket seals the valve cover to the head so as not to leak oil.
the signs of a valve cover leak are oil on the engine oil is the only thing that can leak from a leaky valve cover
It is in the driver side valve cover, you must change the valve cover to replace the PVC valve.
* The PCV valve is located in the valve cover. * Detach the hose from the valve cover and pull out the PCV valve
If you are asking because of your valve cover leaking oil, there was a recall on that year valve cover gasket.
